Chemistry 2005 JAMB Past Questions - Question 48: In a flame test for calcium, the flame appears

Correct Answer

D

Explanation

The flame test for calcium typically results in a brick-red flame, which can be observed without the use of a blue glass. The use of a blue glass in this context is not a standard practice for observing the flame color of calcium. Flame tests are usually performed without any colored filters to accurately observe the characteristic color emitted by the metal ions present in the sample.

In general, the flame color of calcium ions is orange-red. The addition of certain substances or impurities can sometimes affect the flame color, but it is not common to use a blue glass specifically for observing the flame color of calcium.
